Also, wanted to share that EHS math department has been utilizing the highly regarded PEA problem sets and materials for most honor math classes, including Algebra 1, Geometry, and A2/Trig for a few years. Pre-Calc and Advanced (AP) Calc currently do not use PEA materials. In addition to employing the Harkness classroom format, DD also noted that her teacher uses the “flipped classroom” which mirrors the PEA curriculum.
